Should bump stocks and suppressors be illegal?

The gunman in the Las Vegas shooting in October reportedly had equipped several AR-15 rifles with what is called a bump stock, which effectively turns a semi-automatic rifle into a weapon capable of automatic fire. Following that tragedy, there has been a great deal of discussion around the legitimate purpose a bump stock might have, as well as the need for a gun owner to equip their firearms with a suppressor. In this podcast segment, Jim and Doug discuss those issues as well as the emerging threats posed by 3-D printers and so-called ghost guns.
